When a problem occurs in the ABS, the ABS warning lamp on
the instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on “Data link connector”. The location of the malfunc-
tion is indicated by the ABS warning lamp flashing.

Drive vehicle over 30 km/h (19 MPH) for at least one minute.

5.
After 3.0 seconds, the ABS warning lamp starts flashing to
indicate the malfunction code No. (See NOTE.)
6.
Verify the location of the malfunction with the malfunction code
chart. Refer to BR-61. Then make the necessary repairs fol-
lowing the diagnostic procedures.
7.
After the malfunctions are repaired, erase the malfunction
codes stored in the control unit. Refer to BR-49.
8.
Rerun the self-diagnostic results mode to verify that the mal-
function codes have been erased.
SBR535E
9.
Disconnect the check terminal from the ground. The self-diag-
nostic results mode is now complete.
10. Check ABS warning lamp for deactivation after driving vehicle
over 30 km/h (19 MPH) for at least one minute.
11. After making certain that ABS warning lamp does not come on,
test the ABS SELF-DIAGNOSIS in a safe area to verify that it
functions properly.
NOTE:
The indication terminates after five minutes.
However, when the ignition switch is turned from “OFF” to “ON”, the
indication starts flashing again.
HOW TO READ SELF-DIAGNOSTIC RESULTS
(MALFUNCTION CODES)
NHBR0108S03
1.
Determine the code No. by counting the number of times the
ABS warning lamp flashes on and off.
2.
When several malfunctions occur at one time, up to three code
numbers can be stored; the latest malfunction will be indicated
first.
3.
The indication begins with the start code 12. After that a maxi-
mum of three code numbers appear in the order of the latest
one first. The indication then returns to the start code 12 to
repeat (the indication will stay on for five minutes at the most).

terminal ground must last more than 1 second. The ABS warn-
ing lamp goes out after the erase operation has been com-
pleted.
